IMPROVED BED-BOTTOM.

TO ALL TO WHOM THESE PRESENTSSHALL COME:

Be it known that I, TAYLOR P. THOMPSON, of Charlestown, in the county of Middlesex, and State of lilassachusetts, havcinvcntcd a non useful Improvement in Spring-Ped Bottoms; and do hereby declarethe following to be a full, clear, and exact .description thereof, reference being had to the accompanying drawings, in Awhich Figure I is a. longitudinal section, and

Figure 2 a transverse section of bedstead provided with my invention. p

Figure 3 is a-top view of the same. A

Figure 4 is a representation of one of the spring-sockets, to be hereinafter described.

This invention is an improvement in that class of spring-bed bottoms in which a series of wooden slats is employed for supporting the bed, the object` of this invention being to produce a. simple, durable, and eiiicient bcd-bottom. It consists in combining with the slats a series ot` metallic slotted sockets secured to the rails of' the bodstead, and containing a coiled spring, upon the top of which the end of the Slat rests, in manner and for the purpose as hereinafterdescribed. t I 'V v i In the drawings above referred to as illustrating my invention, the bedstead is shown at A' as composed of thc usual head and foot-boards a b and side and end rails'c c and d LZ. A series of metallic sockets, e e c e, etc., is secured to the inside of thc rails c c, a spiral spring, f, beingl applied within each Sockctand resting l upon its bottom, the upper end oi' the spring extending nearly to the top of the socket'. The wooden slats are shown at g g getc., as having their ends formed with a head or rounded projection to extend int-o the tops ,of the sockets, a slot, z, being formed in the inner face of each socket to alloiv of the vertical movements of the slat. In a bedbott0m constructed as above described I gain the benefit of the elasticity both of the slats and of the spiral springs. The metallic sockets serve to support the ends of the slats and the springs, and while allow ing free vertical movements of the slats, they guide'and sustain the springs, and prevent them from being:r crippled or misplaced. Should any of the springs become set while exposed to the weight of the occupant of the bed, they may be changed to other portions of the bed, and their places supplied with the springs removed therefrom and which have not been subject to such strain. The slats and sockets may be applied with equal ease to the end rails ot' the bcds'tead, although more beneficial results are obtained by the disposition shown in the drawings.

I would remark that a portion o t" the slats and their sockets may, if desirable, be applied to a movable frame hinged to tlie side rail, and so as to be elevated into an inclined position, for supporting aninvalid or sick person. I would also remark that the springs ff, etc., may be supported by means of a stud or pin, in place of the socket, a hole being made in the end of the slat for reception of the pin.

A spring-bed bottom, made as described, is strong, durable, and ciicient, and can be produced at'small cost, and will, I believe, be of public'benetitv and utility.

I claim the combination, with the slotted cylindrical sockets and springs contained within the same, the slats having heads or knobs on their ends, fitting into the said sockets under the arrangement described, so that, while the said slats are capable of a free vertical play,'their heads shall at all times be held within the said sockets,

as specified. y
